autoap disable

K i'm kinda dumb here but anyone out there who can tell me how to disable and enable autoap in version24 micro? I have the trick setup with a wrt54g in repeater mode and have installed it on a programmable TV rotor. My plight is the fact that sometimes I would like to keep my connection with a certain ssid but when a signal comes blasting in thats a little TOO healthy, it sets the unit to that AP. By the way, is there also a way to set access points with the same ssid and different Mac addresses? I have 4 hotspots with the same ssid. I got a jungle of wifi around me!!!!
